Wow !

The signal that hit most of our vision, over its’ success of being decoded, is the Wow! signal. On August 15, 1977, a strong narrow band radio signal was received by the Big Ear Radio Telescope of the Ohio State University, United States, then assigned to a SETI project (Search for Extra-Terrestrial Intelligence). Various hypotheses have been drawn over the possibility of a natural origin that has not been completely discounted, assuming the Wow! signal to be considered the best candidate for an alien radio transmission ever received. Astronomer Jerry R. Ehman circled an alphanumeric sequence, 6EQUJ5, which represents the intensity variation of the radio signal over time, measured as unit less signal-to-noise ratio and ranging from 0 to 36, with the noise averaged over the previous few minutes. Each individual character corresponds to a sample of the signal, taken every 12 seconds. It’s strange, over how the scientists did not just think it could mean something but felt it was the ut…

UFO Ice discs?

Physics causes some strange phenomena, like slowly-rotating discs of ice on a frozen river that resemble UFO saucers. But have no fear, science is here to explain away your excitement.Michigan resident Jason Robinson spotted and filmed an eerie phenomenon in the Pine River in Vestaburg, Michigan, as reported Sunday on MLive.com. Similar discs of spinning ice have been documented before—the Associated Press spotted one back in 2013, for example. While your first guess might be aliens, last year, scientists learned that physics governs these spooky plates’ behavior.Surprisingly, the physical behavior of melting ice cooling the surrounding river water—not the motion of the river itself—drives the turntable.A team of physicists from the University of Liège recreated the spinning ice scenario in miniature by putting a 3.35-inch disc of ice in a one foot-wide temperature-controlled bath. In one experiment, the ice floated on its own, and in another, the researchers controlled things a bit …

The Cochno Stone

Archaeologists in Glasgow, Scotland, briefly excavated and then reburied a 5,000-year-old slab of stone that contains incised swirling geometric decorations..The Cochno Stone, which measures 43 feet by 26 feet, contains swirling decorations, also called "cup and ring marks." The stone and its decorations have been known to people in the area since at least the 19th century. Decorations similar to these swirls have been found at other prehistoric sites around the world; however, the examples incised in the Cochno Stone are considered to comprise "one of the best examples" of such art in Europe, according to a statement by the University of Glasgow, which led the new study. The stone slab was fully unearthed in West Dunbartonshire by Rev. James Harvey in 1887. By 1965, the stone had been vandalized with graffiti and damaged by the elements, so a team of archaeologists buried it beneath the dirt in order to protect the artwork . This summer's two-week re-excavati…
